Could this be done to petrol engines if there is a benfit... just did a quick wiki on it and it's exhaust gas recirculation which in your diesel case replaces some excess oxygen so I can see why you'd want to turn it off so you'd get a bigger bang in the combustion chamber but says for petrol it displaces the amount of combustible matter in the cylinder. Is that good?

i wouldent like to say on this one, i mean principle is the same...... but instead of a vac pipe running from a vac pump, yours will be running of the inlet manifold i would say best thing to do is before making major mods like this.

you know you can buy brake pipe clamps try to squaze the pipe with that first to test if you get any faults, with out seeing the engine and where its going i cant really tell aslong as that pipes not going anywhere else exsample your brake servo, but from looking at that pic im assming it can be done like that. but with peotrol you have got you cat, and its all related with emissions, so as i say just try and squaze the pipe first before anything, incase it starts running rough or eml, or your emissions go through the roof, then at least you can just unclamp it.

Just a thought.... could you fit a thing to put methanol into the EGR so instead of sucking in exhaust fumes it would be sucking in methanol and adding it into the air mixture.

Probably wouldn't work as I don't know much about diesels

Oh an in terms of petrols I've been doing some reading and apparently EGR's were only added after EU changes to keep exhaust emissions down. So an earlier model wouldn't have it on. And turbo petrols don't even have one.

And as someone quoted on a site " why would you want hot exhaust gasses being added to the air intake when we all know cars prefer cold air..."

urmm i see what you mean but.... if you was gonna do that you might aswell blank the egr from the turbo and then tap in to the inlet manifold with methanol then its direct injection and will go stright in to the engine, rather then going through pipes and get a lag or late responsponse, obviously your probaly talking milliseconds but still lol, easy option i would say is inlet mani tho for your anwser lol, hope it helps

So that egr valve is similar to the original one questioned? Just in a different place?

the picture in james picture is the one in question its not in a diffrent place. the only thing i would say is diffrent is on the back of the engine there it has a gold looking cylinder pipe from the egr... the 306 one is just a stright pipe but thats nothing it does same thing, but part from that its identical.

Sorry lol, i was strangly thinking this was the thread with the 1.8l engine in... I'm losing the plot mate..
